RS485 Regenerative Dc Electronic Load For Electric Vehicle Battery Pack

Regenerative Type DC Electronic Load for Electric Vehicle Battery Pack

Equipment Overview

SNELD series regenerative DC electronic load adopts high-frequency PWM rectification and two-way DCDC conversion technology to achieve high-precision, programmable load characteristics, and 100% of the input end energy is fed back to the grid. It has the characteristics of high input power factor and fast dynamic response. This series of loads can be widely used in discharge aging tests such as fuel cell stacks, fuel cell engine systems, power battery packs, and charging stations.

Technical Parameters

Main Features

1. Adopt high frequency PWM rectification and bidirectional DCDC technology, pure digital control, strong function and high reliability.

2. Four output modes: constant current (CC), constant voltage (CV), constant power (CP), and constant resistance (CR).

3. The current switching response speed is fast, which can meet the fuel cell test requirements.

4. Possesses low-voltage and high-current load capacity, which can meet the fuel cell stack test requirements.

5. Using PWM conversion technology, 100% of the absorbed energy is fed back to the grid, energy saving and emission reduction, and high input power factor, no pollution to the grid.

6. Multiple protection functions: output under voltage, phase loss, output over voltage, IGBT over heat, IGBT over current, over temperature protection, short circuit current limit protection.
